[125] Foy exaggerates considerably when he says that from July 12 onward ‘the blockade of Saragossa was complete’ (iii. 300). Reinforcements entered on several subsequent occasions. By July 15, Verdier’s trenches were commencing to work up close to the walls, and the next ten days of the month were occupied in desperate struggles for the convents of San José, of the Capuchins and Trinitarians, which lie outside the city near the Carmen and Porta Quemada gates. By the twenty-fourth the French had occupied them, connected them with their approaches, and begun to establish in them breaching batteries. Another, but less powerful, attack was directed against the Portillo gate. The mortars and howitzers bombarded the city continuously from the first to the third. But it was not till the dawn of August 4 that the heavy guns were ready to begin their task of battering down the gates and walls of Saragossa. After five hours of steady firing the Spanish batteries were silenced, and several breaches had been made, mostly in or about the Convent of Santa Engracia, at the southernmost point of the city. The streets behind it had been terribly shattered by the previous bombardment, and many buildings destroyed, notably the central hospital, from which the Spaniards had to remove, under a terrible hail of shells, more than 500 sick and wounded, as well as a number of lunatics and idiots: the institution had been used as an asylum before the outbreak of the war. Many of these unfortunate creatures were destroyed by the besiegers’ fire[126], as were also no small number of the wounded and of their doctors and nurses. [126] Caballero and Toreño put the distressing scenes at the hospital and the escape of the lunatics during the assault on the 4th, but Arteche seems more correct in placing them during the bombardment of the preceding day.
